[0025] Here's how it works:

[0026] First, the new device is placed at the desired location and connected to the circuit;

[0027] Second, the conveyor belt 1 conveys the mobile phone shell by setting an interval. When the collected shell is transported to the lower side of the paint spraying structure 6, the cylinder 4 is extended, and the telescopic rod 5 is used to drive the mounting plate 61 to move downward, the hose 62 is extended, and the solenoid valve 64 is opened, so that the paint inside the paint storage chamber 63 is transported to the paint spray nozzle 65 through the hose 62, and the paint spray nozzle 65 sprays the paint onto the mobile phone shell through the pattern plate 667. After the painting is completed, the cylinder 4 drives the mounting plate 61 to move upward, and the conveyor belt 1 drives the collected shell to move right to the lower side of the drying device 67 for drying. The motor 662 drives the rotating shaft 663 to rotate, and the rotating shaft 663 drives the rotating plate 664 to rotate. The rotating plate 664 drives the pattern plate 667 to rotate, so that the paint liquid on the upper side of the pattern plate 667 can be poured into the inside of the collecting box 7 for collection, thereby avoiding the formation of a dry paint layer on the rotating plate 664 and the pattern plate 667, which affects the uniformity and quality of the paint spraying;

[0028] Third, by pushing the push rod 6686 of the two sets of limiting structures 668, the push rod 6686 slides along the second sliding groove 6682, and at the same time, the push rod 6686 drives the sliding block 6683 to slide along the first sliding groove 6681, and the sliding block 6683 drives the card block 6684 to be retracted into the interior of the first sliding groove 6681, and at the same time, the sliding block 6683 squeezes the spring 6685 to cause the spring 6685 to contract. At this time, the limitation on the pattern plate 667 is released, thereby achieving the effect of facilitating the replacement of the pattern plate 667.
